The UBIK Session Authentication Management (USAM) is a mechanism for managing all connected users logged in to one or more UBIK databases. There are three general modes of session authentication:
Single Local Authentication
This means that no explicit authorization mechanism is used. The user's session is a single session which cannot be terminated by another user or the system itself.
LAS (Local Authentication Service)
When a local authentication is used, the session management service and the data service share the one database. This does not mean that a local authentication service has to be in the same location as the data webservice, only the database connection for both services have to be configured to use the same connection.
GAS (Global Authentication Service)
Global session management means that the session management is managing connections to one or more databases via a separate database used to manage these sessions.
